Wrong codegen behavior when trying to inject instance with Qualifier but component has instance without Qualifier in its dependencies

Hello!

I’ve just faced an issue when tried to inject one instance with qualifier when my component has another component which provides instance without qualifier in its dependencies.

For instance, there’s two components:

ComponentA ComponentB (depends on ComponentA).

ComponentA provides Sample without qualifier. ComponentB provides Sample with qualifier @BImpl

I’m trying to inject Sample with qualifier to Container:

class Container {

    @Inject
    lateinit var sampleA: Sample
    @Inject
    @BImpl
    lateinit var sampleB: Sample

}

But both samples are ImplA.

Is it intended behavior? Because for me this is unexpected and seem like a bug.

Here’s a sample project: https://github.com/IlyaGulya/Dagger2QualifierBugSample Please run test dagger2qualifiersample.TestSample.example() to reproduce the issue. Both calls prints ImplA.

Reopening this as it’s probably a good area for us to document

Closing since this is fixed in https://github.com/google/dagger/releases/tag/dagger-2.25.2 and there’s no more need to document it.
